I do have a crop and I can hold a crop just fine though I want to use the dressage whip because I want to tap BEHIND my leg and not his shoulder because his problem is that he is not listening to my leg aids well, and I know this is sort of a band-aid for a horse with a training issue.
I have a huge problem with keeping him forward, he is the laziest thoroughbred I have ever seen, he walks like he's going to a funeral, I've corrected this by bumping him with the heels until he walks with the pace I feel is right, BUT here is an issue, when I ask him for the trot He DOES NOT take me seriously and will throw his head in a fit, he does what I ask but I have to get on him for it and this makes him throw his head and offset my hold on the reins, My trainer thinks he does this because he thinks I am going to pull on his face, but it is the exact opposite I GIVE him the rein when I ask him to trot or move forward. How do I correct this? I have found the dressage whip helps with me steering cause he likes to move his hindquarters out and cut corners and also it helps him behave a teeny bit more responsively to my leg if I wave it a little... But he is still not taking me seriously and I have done a lot of groundwork with him, its just he lacks respect when Im in the saddle.
